\section{Introduction}

\emph{to be written}




\section{Other changes to the \LaTeX{} kernel}


\subsection{\cs{end}\texttt{\textbraceleft document\textbraceright}
  should always start in v-mode}

Until now \verb=\end{document}= executed the code from the
\cs{AtEndDocument} hook as its first action. This meant that it was
executed in horizontal mode if the user left no empty line after the
last paragraph.  As a result one could get a spurious space added, for
example, when that code contained a \cs{write} statement. This was
fixed and now \cs{enddocument} first issues a \cs{par} to ensure that
it always starts out in vertical mode.

\subsection{Allow extra space between name and address in \pkg{letter} class}

The \cs{opening} command in the the \pkg{letter} class expects the
name and address to be separated by \verb=\\= but it didn't allow to
use an optional argument at this point to add some extra space after
the name. The coding has now been slightly altered to allow for this.

\subsection{Improved copy\&paste support for \pdfTeX{} documents}

Copying from and searching in PDF files works more reliably, if these
files contain ToUnicode CMaps which help the viewer to map glyphs to
(Unicode) characters. These CMaps already were written for OpenType
font in \XeTeX{} and \LuaTeX{}. Now \pdfTeX's support for generating
these maps is enabled by default too.
